Hi, I’ve had this experience a few times already, moving between devices. I connect to my account from a new device and receive only the unencrypted messages. Then I send the autocrypt setup from my previous device, and receive it on the new. I cannot see the old encrypted messages, though, only new ones.
It would be great to have a button somewhere to reload the entire history of the account, essentially, clear the cache and start reading IMAP from start. This feature should also be offered as an option after importing keys or receiving autocrypt setup message.
Thanks a lot, folks
